Signs That You May Have Unintentionally Had COVID-19

The coronavirus still spreads all over the world and causes deaths. Deaths in the world have exceeded 3 million, and it is unclear when the Covid-19 outbreak will end. The Covid-19 virus may have existed for longer than expected. It is thought that there may be many people who were infected with the virus before Covid-19 was declared as an epidemic and negatively affected all areas of life, but survived without knowing it, and caused the virus to spread because it did not show symptoms. Since antibodies are formed in these people, some immunity may have developed. Here are the signs that people may have had Covid-19 without realizing it:

Signs You May Have Unintentionally Had COVID-19A Bad Cold

Colds are not uncommon during the winter months. However, there is a possibility that those who have experienced longer-than-normal colds, constant fatigue, and body pain in late 2019 or early 2020 may have actually had Covid-19. One way to tell the difference is that Covid stays for 2 weeks or longer, while a cold usually only lasts for a few days. Unlike the common cold, Covid can cause fever and make breathing difficult.

Bloody or Red, Watery Eyes

During the pandemic, frequent washing of the hands and avoiding touching the face were requested. One reason is that Covid-19 can affect the eyes. If you have conjunctivitis (pink eye), watery eyes, or blurred vision, it may be caused by a virus. What distinguishes eye redness, which may be a symptom of Covid-19, from infections caused by other viruses, is that it can be seen with headache and fever.

Brain Fog

Covid is known to cause memory and cognitive effects. Some even report memory loss and difficulty performing routine tasks. Confusion, instability, trouble concentrating, or just having trouble remembering things can also be a Covid complication. Although brain fog can be caused by other medical problems, not being able to focus clearly, remember things, or do simple daily tasks without any reason can be a reason to suspect Covid.

Unusual, Persistent CoughSigns You May Have Unintentionally Had COVID-19

Since the virus enters through the respiratory tract, a cough symptom occurs first. This is an early sign of Covid-19 and is different from the cough caused by the common cold. It starts off mild but gets worse over the next week. If there is a dry cough that takes a long time to pass, this may indicate that the person has Covid-19. The survivors and survivors of the disease explain that dry cough is different and permanent than a normal cough, the voice can change, and cough can be very difficult to control.

Continuously Fluctuating High Fever

Fever is not an obvious sign in all cases of Covid-19, but those suffering from an infected fever usually have a high temperature that can last between 37.22-39.44 degrees Celsius. The temperature rise may come and go, it may continue for 4 or 5 days or even more, and there may be chills and chills with fever. Experts suggest that feeling hot when the person’s back or chest is touched may also be a sign of Covid 19.

Sudden Odor or Loss of Taste

It is known that the SARS-COV-2 virus (new coronavirus) can disrupt the sense of smell and prevent the taste of food. If the taste of food and beverages is different than normal or if you cannot smell for a few weeks, the person may be infected. If the food could not be tasted for any reason in the past year and strange, different smells were taken, probably Covid-19 was passed. Approximately 80% of people who test positive have these problems, and this is usually a sign of a mild case.

Shortness of breathSigns You May Have Unintentionally Had COVID-19

Difficulty breathing and shortness of breath are not usually a symptom of a cold or flu, but feeling like you can’t breathe is common in Covid-19. Breathing difficulties may also be experienced in cases such as bronchitis, anxiety or panic attacks, but with Covid, shortness of breath takes longer than a panic attack. It also comes with flu-like symptoms. In addition to shortness of breath, rapid breathing and palpitations can be seen. These are signs that the person may have had Covid-19 without realizing it. Shortness of breath is common in elderly people, those with one or more comorbidities (coexistence of one or more disorders with an underlying disease).

Heart Palpitations or Chest Pain

Covid-19 can also affect the heart, causing palpitations or blunting. You may also experience chest tightness. Attacks like this can continue for up to 2 weeks in mild cases, and up to 5 or 6 weeks in more severe cases.

Gastrointestinal Problemler

Researchers think that a certain portion of people who have gastrointestinal problems such as nausea, diarrhea, abdominal cramps, loss of appetite and who cannot be diagnosed with certainty may have had Covid-19.

Fatigue and WeaknessSigns That You May Have Unintentionally Had COVID-19

Fatigue and fatigue are a common symptom of Covid-19. Therefore, this type of extreme fatigue that does not improve with plenty of sleep may indicate that this virus is in the body. This feeling can come back after days and sometimes weeks. Scientists are trying to find out how SARS-COV-2 causes fatigue. Tiredness and body aches that last a few days that make it difficult to perform daily tasks may be a sign that the person may have had Covid-19 without realizing it.

Antibody Test

Antibodies are proteins that the body produces to help fight an infection. The only way to know for sure if you have passed Covid-19 is to have the blood tested to see if there are antibodies that fight the virus. Scientists are not sure how well the antibodies produced in the body will protect people from getting the virus again. However, some studies show that people with these antibodies are less likely to get Covid again.


The virus change (also called a mutation) does not appear to greatly affect the symptoms caused by the virus or the severity of the disease. The only difference, it seems, is that the mutation has made it easier for the virus to spread from person to person. The symptoms of this last form of Covid-19 are the same as the original. Therefore, there is no easy way to know which strain a person has.
